Course Description
COURSE CONTENTS

Course contents: Ideal Operational Amplifiers (Op-Amps) are a key topic, along with their inverting and non-inverting configurations. Understanding Op-Amp non-idealities is also crucial. Applications of OpAmps include filters, differentiators, integrators, and analysis of their frequency response using Bode plots. The frequency response of amplifiers covers basic concepts, and how amplifiers behave at both low and high frequencies. Field-effect Transistors (FETs) are another important component, specifically the junction FET (JFET), including its characteristics, parameters, and biasing. The Metal-OxideSemiconductor FET (MOSFET) is also covered, detailing its characteristics, parameters, and biasing techniques. Small-signal FET amplifiers are explored, focusing on their operation, FET amplification principles, and specific configurations like common-source, common-drain, and common-gate amplifiers, as well as their frequency response.Practical aspects involve familiarization with laboratory instruments and analog circuit simulation software, used for measuring DC voltages and currents. The basic characteristics of operational amplifiers and comparators are examined, leading to the design of amplifiers using operational amplifiers. The fundamental principles of amplification are also discussed. Further topics include MOSFET characteristics and various applications, and the design of an audio frequency amplifier using a JFET. The curriculum also covers RC transient circuits, filters, and their frequency response, as well as LC circuits, resonance, and transformers, with a focus on both parallel and series resonant circuits.

LEARNING OUTCOMES

At the end of the course the student will be able to:

  • describe the operation of Operational Amplifiers.
  • calculate currents and voltages in circuits with Operational Amplifiers in their various configurations.
  • describe the physical operation and calculate the currents and voltages of semiconductor components in MOSFET transistor applications, including amplifiers.
  • calculate the currents and voltages of components in MOSFET transistor amplifier circuits, as well as the characteristics of the amplifiers.
  • implement a designed circuit and use a multimeter, oscilloscope, function generator, and power supply to take measurements and plot characteristic curves, especially for amplifier circuits with bipolar transistors and/or MOSFETs.
ASSESSMENT

Assessment: Assessment will be by written exams at the end of the semester or by assignments, or by written exams and assignments. The assignments, if combined with exams, will contribute to the final grade with a percentage ranging between 40% and 60%.
